INTERNALCOMBUSTION ENGINE,

vTo all/whom t may concern:

Be it known that I, ELvER'roN W. WEAVER,

la citizen of the United. States, residing` at Cleveland Heights, in tbe county of Cuyahoga and State of Ohio, have invented a cer` tain new and useful improvement in Internal-Combustion Engines, of which the following'is a, full, clear, and exact description.

This invention relates to internal combustion engines. One object ofthe invention is to provide an .engine whichis especially adapted for use .with aeroplanes although not comined to such use. i

permit its being used with its cylinders inverted with respect to the usual upright po l sition. A furtherobject is to provide certain improved constructions associated with the crank case which are in a measure ancillary to the purposes for which the en gine is to be used. Other objects will appea as the description of the invention procee s. v

binations thereof set panying claims.

Reference should 'be had to the accoinpanying drawings forming a part oztthis specification, in which igure 1 is a sideV elevation` of an engine embodying my invention, with portions removed and other portions shown in section; Fig.' 2 is a section upon the'line 2-2 of Fig. 1; Fig. '3 is a secs tional elevation upon the line 3--3 of Fig.l

1; and Fig. 1 is an elevation of-a screen.

Referring to the drawings, -it will be Seen that the various gures disclose a twelvecylinder V-type-engine, and while the invention isparfticularly designed for use in connection with a"V-type of engine, it will be obvious thatthe number of. cylinderserrr ployed is merely a matter of choice.

The cylinders of the engine are arranged in'two rows with their axes forming a V.. These cylinders are generallyprepresented at 1. Surrounding the cylinders `is the usual water jacket 2, and coperating with the end 'of each cylinder is av cylinder head whichis generally represented at 3, this cylinder head being preferably bolted to the cylinder jacket and has provision for the usual valves,

inlet andexhaust passages `for.fuel, spark plug receiving openings, and provisions for water cooling the cylinders and heads.

Specicationcf Letters Patent. A Patented 'Application filed February 10, 1917. Serial No. 147,732.

Generally-speaking, the inventionmay be said to comprise the elements andthe comj forth in thevaccoin-j4 y with the crank casing, as will appear from `such as indicated at 20-in July 29, 1919.

The valves associated with the head of each cylinder are operated by suitable rock@ arms as indicated at 4, and each rocker arm is actuated by a rod 5. Within each cylinder 1 is a piston 6 which has a'I piston rod 7 articulated thereto. And each piston rod is suitably articulated to the crank shaft 8.

. Each cylinder 1 has an extending skirt 1a vwhich as Shown in Figs. 2 and 3 extends into the crank cases and provides Aa wall around the inner end of the cylinder -for preventing the entrance of lubricantinto the cylinder so that the crank case is .divided into'two distinct chambers. j The oor 13 is provided with two or more openings which are indicated at 14. These opcningsare left unobstructed under certain conditionsof use of vthe engine, but may be closed by means of plugs which are indicated -at 15 in Fig-.2.

of thecylinders, are preferably cast 'integral an inspection of-Fig. 3.

Extending longitudinally Aof the crank case and within the chamber 12 thereof there are a series of inclosed portions 15` through which'the cam shaft 16 is adapted ,to extend. The cam shaft entends from one end of the` casing to the other and. is provided with the usual cams which are adapted to engage withjthe rods 5 that operate the rocker arms of the' valves. At suitable places, for accommcdating the rod 5, there are tubular mem bers 17 which are received into threaded necks 18 of the walls. of `the chamber 1.5 which'incloses thecam shaft. These tubes also extend througli suitable openings formed in theouterwall portions of the chamber 12 as indicated at 19 in Fig. 3. Each tube 17 as the engine is operated, as will appear Another object of the invention is to pro- I. videan engine of such construction as to ,I

The cylinders, jor at least the outer walls I forms a housing for itsl valve rod 5, permitting the working or removal or replacement if necessary of the valve operating' rod' without, inv `any way interfering with the 1 crank casing.

The chamber 1 5 which incloses thecani shaft 16, is divided injto a plurality of parts, and between the parts there `are openings Fig. v1. These openings are vprovided for a purpose .which will be later'explained. However'Qin order casing l5 5 f tion of said casingn the oil may be maintained at a uniform tembest working.

The advantages of the construction as shown in the drawings and having the cylinders inverted is manifold. For, one thing, the cooling of the engine is much more easily accomplished than can be done with the cylinders in the upright position, forthe movement of the Water along the cylinders is in the direction in which the water naturally perature for its -moyes bause of the heat supplied thereto by the cylinders. l

Furthermore, .the inverted construction provides an easy access to the cranlshaft and for mah-ing any necessary inspection or repair Y Haring Ithus described. my inyention, what l claim isz-- l. in aninternalcombustion engine, two rows oi cyiinders arranged las a "d, a lubrilcant containing receptacle located between the cylinders and hin the V, and exit means ronithe receptacle whereby lubricant may pass the engine parts to be lubricated. v v 2.
